public AtomMatcher()

Method Details

matches

public abstract boolean matches(IAtom atom1,
 IAtom atom2)

Are the semantics of atom1 compatible with atom2.

Parameters:

atom1 - an atom from a query container

atom2 - an atom from the target container

Returns:

the atom1 can be paired with atom2

forAny

public static AtomMatcher forAny()

Atoms are always compatible.

Returns:

a matcher for which all atoms match

forElement

public static AtomMatcher forElement()

Atoms are compatible if they are the same element.

Returns:

a matcher which checks element compatibility

forQuery

public static AtomMatcher forQuery()

Atoms are compatible if the second atom (atom2) is accepted by the IQueryAtom, atom1.

Returns:

a matcher which checks query atom compatibility
